Double Lake gas station of CNPC’s Tibet branch, 5, 200 meters above sea level, is the highest gas station in the world. It makes a great contribution to the economic development in Tibet.

Shuanghu county, with an average elevation of 5,000 meters, is 640 kilometers away from Lhasa. Covering an area of 116,700 square kilometres, the county has a population of 13,000. The most remarkable characteristic of this county is poor natural conditions, high-cold and oxygen deficit and inconvenient traffic.

Double Lake gas station is the most remote one from CNPC Tibet branch, and it was rebuilt in 2012 with total area of 3,750 square meters, total storage capacity of 200 cubic meters, which includes 100 cubic meters of petrol and diesel respectively. The station has two fuel dispensers. Four regular employees, three policemen and one intern in the station are all Tibetan. It is awarded an advanced gas station by CNPC Tibet branch.
